The prosecution, defence, and the families of the victims had a chance for closing comments. After this, the court officials will retire to consider their verdict.
In 1960 Gustafsson went camping at Lake Bodom in Espoo with the three victims, his friend Seppo Boisman and their girlfriends. The other boy was stabbed to death; the two women were clubbed with rocks. Gustafsson was treated for some injuries, for example, a fractured jaw and a cut cheek.
Prosecutors Tom Ifström and Heli Haapalehto used DNA evidence gathered from Gustafsson's shoes and the youths' camping tent to support their case. The tent was also brought into the courtroom.
Police say that an enraged Gustafsson sliced through the tent with a knife and killed his friends, and then later re-arranged the campsite to make it appear as if he was also a victim. They say jealousy and resentment were the motives, pointing out that one of the girls was found partially undressed at the crime scene.
Defence: Murderer Got Away Gustafsson's defence team says that an unidentified outside assailant was responsible for the murders. They say that there was no argument that evening, or any other motive for Gustafsson to have committed murder. Nils Gustafsson claims he does not remember much about the night in question, but that he is sure of his innocence. Unwitting Confession? Police officer Markku Tuominen testified that he believes Gustafsson unwittingly confessed to the crimes. Tuominen says the admission was made while Gustafsson was in police custody last autumn. He said that a frustrated Gustafsson threw himself on a bed and said, "What's done is done, I'll get 15 years for it." (" Tehty mikä tehty, 15 vuotta tuli"). Another surprise witness testified earlier that Gustafsson had an argument with Boisman on the night in question. She had been camping with friends at a nearby site, and recalls that Gustafsson and the three others joined them for a time. She says that he was drunk, and had a fierce quarrel with his friend. This directly contradicts Gustafsson's account, in which he says the two men and their girlfriends spent a pleasant evening together without any arguments. His lawyer says the surprise witnesses' testimony was flimsy, since she couldn't even recall the names of her companions at her own campsite. The defence also wondered why the witness had kept quiet about this incident over the decades. She replied that once the murders became public, she and her friends swore they would keep the incident to themselves. YLE24, Finnish News Agency
